Abstract

The invention discloses an overlapped sequence valve, which comprises a valve body with certain thickness, wherein a valve core is arranged in the valve body. The overlapped sequence valve is characterized in that one side of the valve body is provided with a pressure detection opening, a pressure meter is connected with the pressure detection opening, the other side of the valve body is provided with a spring, one side, near the valve core, of the spring is provided with a force sensor, the other side of the spring is provided with a regulating screw rod, the spring is arranged at one side of the valve body through an external valve cover, the bottom of the valve body is provided with an oil inlet, an axial hole is formed between the oil inlet and the pressure detection opening, and an oil outlet is formed in the top of the valve body. The overlapped sequence valve has the advantages that the structure is simple, the cost is low, the control deviation is small, and the pressure regulating precision is improved.

Description

technical field [0001] The invention relates to a stacked sequence valve. Background technique [0002] The basic function of the sequence valve is to control the sequential action of multiple actuators. In order to make the actuators accurately realize the sequential action, the sequence valve is required to have high pressure regulation accuracy and small deviation. The traditional superimposed sequence valve uses a spring to adjust the pressure. During the long-term use, the spring will be deformed, which will easily cause large control deviation and reduce the pressure adjustment accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides a superimposed sequence valve, which has simple structure, low cost, small control deviation and improved pressure regulation accuracy. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized t...
